Looking for a WP plugin to modify RSS feed with a given date

Hello, I'm looking for a WP plugin or a script which will take a date as argument of the RSS feed url and then generate a RSS feed with the existing articles only with all the date changed.

Example :
We are the 25th december 2016
A blog has its first post published on 10 January 2016 and then there is one blog post published per week.
The "normal" RSS feed gives us the last X posts until today.
I'd like to get a RSS feed which will take a date as argument, for instance 10th december 2016 and which will return the last X posts as if today was the 25th of january 2016.
So I will add to the "fake" rss feed the argument ?date=2016-12-10
So it will return 3 posts, the one from 10 january, 17 january and 24 january, only the pudDate in the rss feed will be 10 december, 17 december and 24 december.
And if I call this rss feed in 10 days from now (with the same ?date=2016-12-10) it will also display the 4th post from 31 january, only the pubdate will be 31 december.

I hope you understand what I'm looking for and could tell me where to find such a WP plugin or script, because I've been unable to.

Hello, I've looked into the pro version of wpematico, it doesn't say it has this feature in pro. In free it has only the feature of including other rss feeds (feeds fetching) but that's it.
I don't see any mention of the feature I'm talking about.
Could you please confirm that you understood the feature I want and that wpematico pro has it?
It isn't written anywhere on wpematico as far as I could see.
